Please don't call it a "40 sack", cause thats very unnacurate. 40 bucks can get you various amounts. Just learn the prices for regs, mids, and dank.

regs is like 100 an O usually, so 25 a Q.

Mids I don't really know, it varies. Just know that its in between regs and dank, so maybe like an eigth for 25 wouldn't be a bad price.

Dank is like 25 for a half eigth, and 50 for an eigth. So you should get around an eigth of dank if its good.

Then again, prices very greatly. I wish I could get a full O for 50-60. I'm happy with the halves I get for 50 though.
